Former Oregon State outfielder Cole Gillespie is off to a hot start in his first stint with the Arizona Diamondbacks since being called up on April 21.

In ten games, Gillespie is batting .300 with five doubles and on Friday night hit his first major league home run during a 3-2 loss to Milwaukee in Arizona.

The solo blast to right field came in the third inning off starter Yovani Gallardo and temporarily tied the game.

Gillespie, out of West Linn High School, was batting .283 with one home run in 10 games with the Triple A Reno Aces before being called up.

He began last season with the Triple A Nashville Sounds (Milwaukee). During spring training he underwent elbow injury and wound up hitting .242, with seven homers and 27 RBIs before being traded to Arizona in July for infielder Felix Lopez.
